Professor Chen is a fan of goe. Goe is a kind of intellectual game like chess but much more complicated than the latter. He turned his research direction into the field of artificial intelligence for goe since retiring. His goe program, named Handtalk, defeated all opponents in the 1993 International Computer Goe Congress and won as Champion. This is an achievement far greater than all his outcomes in Chemistry. His Handtalk is still the strongest goe programs at present in the world and is being sold widely in the world market. As goe programming is one of the most difficult and interesting topics in the field of artificient intelligence, Professor Chen will struggle for it all his life.
